2:16,17 We may and should direct our prayers, not only to God the Father, through our Lord Jesus Christ, but also to our Lord Jesus Christ himself. And we should pray in his name unto God, not only as his Father, but as our Father in and through him. The love of God in Christ Jesus, is the spring and fountain of all the good we have or hope for. There is good reason for strong consolations, because the saints have good hope through grace. The free grace and mercy of God are what they hope for, and what their hopes are founded on, and not any worth or merit of their own. The more pleasure we take in the word, and works, and ways of God, the more likely we shall be to persevere therein. But, if we are wavering in faith, and of a doubtful mind, halting and faltering in our duty, no wonder that we are strangers to the joys of religion.
17. Comfort your hearts—unsettled as you have been through those who announced the immediate coming of the Lord.
good word and work—The oldest manuscripts invert the order, "work and word." Establishment in these were what the young converts at Thessalonica needed, not fanatical teaching (compare 1Co 15:58).
